What does Cost of Goods Sold mean?

Cost of goods sold (COGS) refers to the direct expenses related to the production of the goods your business sells. This figure includes the materials and labor costs of creating your products. Understanding COGS is essential for an eCommerce business because it directly impacts your profit and shapes your pricing and advertising strategy.

Understanding Cost of Goods Sold

Cost of Goods Sold (COGS) is a direct reflection of the costs that are involved in producing or purchasing the products you sell. Here, you’ll learn what COGS is, how it differs from gross profit, and its significance for your business operations.

Defining COGS

Cost of Goods Sold (COGS) refers to all the direct costs attributable to the production of the goods sold by your company.

This includes the cost of the materials and labor directly used to create the product. For instance, if you’re selling handcrafted jewelry, your COGS would include the price of beads, metals, and the labor used to make the jewelry.

By keeping close track of these figures, you ensure that you accurately calculate your COGS, which is crucial for your income statements.

COGS vs Gross Profit

To understand COGS, it helps to know how it fits into calculating your gross profit. Gross profit is the income left over after subtracting COGS from your revenue:

  • Gross Profit Formula: [Revenue – COGS = Gross Profit]

It’s important not to confuse COGS with expenses from other business areas like marketing or research and development. Those costs are not included in COGS but are considered operating expenses which are deducted from gross profit to determine net income or profit.

Importance for businesses

COGS is critical for your business because it directly affects your profitability.

When you accurately report COGS, you can better understand your product pricing, manage your inventory more effectively, and make informed decisions on cost-cutting measures that can enhance your gross profit.

Moreover, it plays a vital role in your business’s financial assessments, tax returns, and can be an indicator of the overall efficiency of your production process.

Calculation methods

By understanding and applying different calculation methods, you can accurately report your cost of sales and maintain precise inventory records.

COGS formulas

To calculate COGS, you essentially subtract your ending inventory from the sum of your beginning inventory and additional purchases made during the period:

COGS = Beginning Inventory + Purchases – Ending Inventory

Your beginning inventory is the value of inventory that was unsold at the end of the previous period. Purchases include all inventory bought during the period, which can encompass shipping and handling costs. The ending inventory is then the value of unsold goods at the period’s close.


When you have varying costs for inventory items purchased over time, you can choose different assumptions on how you sell them:

  • FIFO (First In, First Out) assumes you sell your oldest inventory first. Considered to mirror the natural flow of inventory, it typically results in a lower COGS and higher profits in times of inflation.
  • LIFO (Last In, First Out) assumes you sell the newest inventory first, leading to a higher COGS and lower profits during inflation. LIFO is not universally accepted under International Financial Reporting Standards (IFRS), so you’ll need to consider if it’s appropriate for your financial reporting needs.

Average cost method

Alternatively, the average cost method can be used where the cost of goods is determined by averaging the cost of all similar items in the inventory. This approach may be more appropriate if your inventory items are largely interchangeable:

COGS = (Beginning Inventory + Purchases) / Total number of units in inventory

Using this method provides a smoothed-out cost of sales figure, minimizing the impact of cost fluctuations over the accounting period.

The components of COGS

When you’re running an eCommerce business, understanding the ins and outs of Cost of Goods Sold (COGS) is crucial.

This will help you get a clear picture of your financial health by accurately representing the costs directly tied to the revenue generated.

Inventory costs

Inventory is the merchandise or goods that you, as an eCommerce retailer, hold with the intention to sell. Inventory costs are the total costs related to storing and managing this inventory until it’s sold.

These costs include the purchase price and any additional costs necessary to get the items ready for sale, such as:

  • Freight and shipping
  • Handling and storage
  • Cost of purchase orders

It’s important to regularly track your inventory levels and costs to prevent stockouts or excessive surplus.

Labor and materials

When considering COGS, two crucial components you must account for are labor and materials.

For labor, you need to include:

  • Direct labor costs: This is the compensation you pay your workers who are directly involved in producing or packing the items you sell. This can range from hourly wages to salaries, including benefits such as pensions if applicable.

Materials encompass:

  • Material expense: This refers to the cost of raw materials or parts that go directly into producing your products. In your case, these could be anything from fabrics for clothing to electronic components for gadgets.

Both labor and materials are direct costs associated with the production of goods.

Manufacturing and overhead expenses

Lastly, manufacturing and overhead expenses are critical parts of COGS for your eCommerce business.

  • Manufacturing costs: This includes the direct costs of producing your products, from the factory floor to the machinery used in the production.
  • Overhead costs: This broader category includes all the indirect costs that are not tied to a specific product but are necessary for overall operations, such as:
    • Facility rent or mortgage
    • Utilities
    • Equipment depreciation

Identifying and allocating these expenses correctly can lead to a more accurate calculation of your COGS and, consequently, a clearer understanding of your gross profit.

Accounting for COGS

When managing your eCommerce business, understanding how the Cost of Goods Sold (COGS) affects your financial statements is crucial. It’s not just a line item on your income statement; it’s a core factor in calculating your taxable income and net profits.

Financial statements impact

COGS is a key figure on your income statement that reflects the direct costs associated with the production and sale of your products.

To calculate it, you start with the beginning inventory cost, add purchases during the period, and then subtract the ending inventory. This calculation yields the total product cost that was expensed for the goods sold during the period, which in turn affects your net income as follows:

  1. Revenue – Represents the total amount of income generated from sales.
  2. COGS – The direct costs tied to the creation of products sold.
  3. Gross Profit – Calculated as Revenue minus COGS.
  4. Operating Expenses – Costs not directly tied to production, such as marketing and salaries.
  5. Net Income – What remains after all expenses, including COGS, are subtracted from Revenue.

The lower your COGS, the higher your gross profit.

Subsequently, this can lead to increased net income, assuming other expenses remain constant.

COGS and tax reporting

When you report your earnings to the Internal Revenue Service (IRS), COGS can be a deductible business expense that directly reduces your taxable income.

The way you calculate COGS must comply with Generally Accepted Accounting Principles (GAAP), ensuring consistency and comparability in financial reporting.

Here is the process:

  • Begin with your Inventory at Start of Year.
  • Add any Purchases and Other Costs.
  • Subtract Inventory at End of Year.

The resulting figure is your COGS for the year, which you’ll report on your tax forms. It’s important to keep detailed records to support your COGS calculations in case of an IRS audit.

By accurately reporting this figure, you properly lower your taxable income, which can result in a reduction of your taxes owed.

As such, COGS is not just an element of profit calculation but also a significant component in determining your business’s tax liability.

Managing COGS in eCommerce

In eCommerce, managing your cost of goods sold (COGS) is crucial to maximizing your gross margin and profit margin.

By focusing on improving efficiency, refining pricing strategies, and optimizing inventory management, you can positively impact your business’s financial health.

Improving efficiency

To boost your efficiency, start by examining your production and fulfillment processes for any inefficiencies.

By streamlining these operations, you can reduce labor costs and materials waste, which are key components of COGS. Adopting technology-driven solutions like automation can speed up production while ensuring consistent quality.

Boosting your efficiency can lead to a higher inventory turnover rate, which means more sales and potentially greater profits without necessarily increasing inventory costs.

  • Streamlined operations: Reduced labor costs, less waste
  • Automation: Consistent quality, increased production speed
  • Higher inventory turnover rate: More sales, potential for increased profits

Pricing strategies

Your pricing strategy directly impacts your profit margin, as it must cover COGS and contribute to your business’s overall financial success.

A data-driven approach to pricing can help you set competitive prices that also ensure profitability.

Temporary discounts might spur sales, but maintain a focus on the long-term sustainability of your pricing model.

  • Data-driven pricing: Reflects market trends, covers COGS
  • Competitive pricing: Attracts customers, ensures profitability
  • Sustainability: Avoids long-term impact on profit margins from discounts

Inventory management

Effective inventory management is a balancing act. You want to have enough stock to meet demand without tying up too much capital in unsold products.

  • Analyze your inventory turnover to understand how quickly stock is sold, and adjust your purchasing accordingly. Aim for a lean inventory that corresponds with your sales patterns. This helps to minimize inventory costs while ensuring product availability for your customers.
    • Balanced stock levels: Meet demand, avoid excess
    • Lean inventory: Reduces costs, aligns with sales patterns
    • Inventory turnover analysis: Adjusts purchasing, optimizes stock levels

COGS in different industry sectors

Cost of Goods Sold (COGS) varies by industry because the types of costs incurred relate directly to how a company produces or acquires its products.

In service sectors, COGS relates more to labor costs, while in manufacturing and retail, it encompasses both materials and labor.

Services based COGS

In the service industry, your COGS will primarily consist of the labor costs of those employees or contractors who deliver the service directly to your customers.

Additionally, any parts or materials that are used exclusively in the delivery of a service are included.

For instance, if you run a web hosting service, your COGS might include server costs, along with the direct labor involved in maintaining those servers.

Manufacturing and retail COGS

For a manufacturer, COGS includes raw material costs, direct labor required to make the product, and any overhead related to the production process.

Operating expenses, like rent and utilities of the manufacturing facilities, though significant, are not counted in COGS but rather in other expense categories.

Retailers calculate COGS by adding the price paid for the product to the costs to get it to the shelf.

This includes shipping and handling, and for an eCommerce business, packaging materials might also be incorporated.

If you own an online store selling handmade jewelry, COGS would encompass the cost of raw materials such as metal and stones, as well as the labor to create each piece.

Common challenges with COGS

When dealing with the Cost of Goods Sold (COGS) in the eCommerce industry, you may encounter a few common challenges. These challenges can affect your profitability and the accuracy of your financial reporting. Let’s explore them in detail.

Indirect costs allocation

Allocating indirect costs to specific products can be complex. This is because you must determine the appropriate method to assign costs in a way that reflects their actual consumption.

For example, a weighted average approach could be utilized to allocate storage costs, especially if you deal with a large inventory that fluctuates in size.

Variable vs fixed costs

Understanding and categorizing costs into variable and fixed can be tricky.

Variable costs change with the level of output, like the cost of raw materials that directly increase as you produce more goods.

Fixed costs, such as rent, remain consistent regardless of your sales volume.

In eCommerce, where sales can be unpredictable, distinguishing between variable cost and fixed cost is crucial. This is for pricing your products correctly and maintaining healthy profit margins.

Inventory valuation challenges

Finally, inventory valuation presents its own set of challenges. Costs fluctuate, and you must decide on a valuation method that best reflects your cost of goods sold.

Do you choose First-In, First-Out (FIFO), Last-In, First-Out (LIFO), or a weighted average cost method?

Each approach has implications for your COGS, especially during periods of inflation or deflation, as it impacts how you report income and pay taxes. You’ll need to maintain consistent and meticulous records to ensure accurate COGS calculation.

COGS and business strategy

When you manage an eCommerce business, understanding the cost of goods sold (COGS) helps you determine your profitability and informs vital strategic decisions.

Impact on profit margins

Your profit margin is a clear indicator of your eCommerce business’s financial health.

Since COGS directly affects your gross profit, it’s important to monitor these expenses closely.

To calculate your gross profit, subtract the COGS from your sales revenue:

  • Gross Profit = Sales Revenue – COGS

By maintaining efficient COGS, you can improve your gross margin, giving your business a competitive edge and the ability to invest in growth opportunities.

Investor considerations

Investors often scrutinize your COGS to assess performance and sustainability. They are keen on the relationship between your COGS and total revenue.

A lower COGS as a percentage of sales indicates higher efficiency and profitability. Here’s what they look for in simple terms:

  • COGS/Revenue Ratio = (COGS / Sales Revenue) * 100

A low ratio means your e-commerce business retains more from each dollar of sales, signaling potential for better profit margins and investment returns.

Frequently Asked Questions

This section addresses common inquiries about the cost of goods sold, helping you better understand its calculation, accounting treatment, and reporting.

To calculate the cost of goods sold (COGS) from sales and gross profit, you’ll subtract the gross profit from your total sales. For example, if your sales are $100,000 and the gross profit is $60,000, your COGS would be $40,000.

The cost of goods sold is typically reflected on the income statement. It’s recorded directly under the revenue section to calculate the gross profit of your business.

Expenses in COGS include the direct costs associated with producing the goods your e-commerce business sells, like raw materials and direct labor. You’ll also consider expenses like the freight cost for transporting raw materials.

The cost of goods sold is considered an expense. It’s the total cost of producing the goods your business sells and is deducted from your revenues to determine gross profit.

In accounting, you would record the cost of goods sold with a debit to the COGS account and a credit to your inventory account at the time of sale. This reflects the decrease in inventory and recognition of the expense.

Let’s say you sell handmade jewelry. If you start with an inventory worth $5,000, you would add the cost of any additional materials you purchased. If you bought additional materials worth $1,000 and ended with inventory worth $2,000, your COGS would be $4,000 ($5,000 + $1,000 – $2,000). This reflects the cost of the inventory you have sold.
